ANSI/TIA/EIA-570-A : Residential Telecommunications
Cabling Standard
This document standardizes requirements for residential telecommunications
cabling. These requirements are based on the facilities that
are necessary for existing and emerging telecommunications
services. Cabling specifications for voice, video, data, home
automation, multimedia, security, audio, HVAC are made available.
The standard is for new construction, additions, and remodeled
single and multi-tenant residential buildings.
Grades of Residential Cabling:
Grade 1-provides a generic cabling system for telephone, satellite,
CATV and data services. Grade 1 specifies a minimum of one
twisted pair cable and associated connecting hardware (Category
3, Category 5 is recommended) and one coaxial cable (75 ohm)
configured in a star topology.
Grade 2- provides a generic cabling system for basic, advanced,
and multimedia services. Grade 2 specifies a minimum of two
4-pair UTP cable and associated connecting hardware (Category
5, Category 5e recommended), two coaxial cables (75 ohm),
and an optional 2-pair optical fiber cable all configured
in a star topology.
Recognized Backbone Cables for Multi-tenant/Campus Infrastructure:
100W Twisted Pair Balanced Cabling
62.5/125mm multi-mode optical fiber
50/125mm multi-mode optical fiber
Single-mode optical fiber
Hard-line coaxial
RG 6 and RG 11 type coaxial
A star topology should be configured for twisted pair
and optical fiber backbone cabling. Coaxial backbone cables
can be configured in a star or bus topology.
